ITEM 2.02.  RESULTS OF OPERATIONS AND FINANCIAL CONDITION.

         On February 23, 2005, Building Materials Corporation of America ("BMCA"
or the "Company") issued a news release announcing its earnings for the fourth
quarter and fiscal year ended December 31, 2004. A copy of the news release is
furnished herewith as Exhibit 99.1.

         The news release contains information regarding non-GAAP financial
measures. As used herein, "GAAP" refers to U.S. generally accepted accounting
principles. The Company uses non-GAAP financial measures to eliminate the effect
of certain other operating gains and charges on reported operating income. The
non-GAAP financial measures are provided to assist the reader in better
understanding our operational performance. The non-GAAP financial measures
included in our news release have been reconciled to the most directly
comparable GAAP financial measure as is required under Regulation G regarding
the use of such financial measures. These non-GAAP measures should be considered
in addition to, and not as a substitute, or superior to, operating income or
other measures of financial performance in accordance with generally accepted
accounting principles.

         This information is being furnished to the Commission and is not
"filed" pursuant to Section 18 of the Securities Exchange Act of 1934, as
amended (the "Exchange Act"), and is not incorporated by reference in any filing
under the Securities Act of 1933, as amended or the Exchange Act, except as
shall be set forth by specific reference in such a filing. Additionally, the
submission of this report on Form 8-K is not an admission as to the materiality
of any information in this report.
